We've had plenty of manga discussing the realities of being gay, lesbian, trans, and genderqueer, so it's only fair to see some manga on asexuality as well.
IS LOVE THE ANSWER? (Kimi no Sekai ni Koi wa nai), by Uta Isaki. First published in 2020 and first published in North America in 2023.
PLOT:
Chika could never understand what people wanted from her. She tried to date boys in high school, only to feel nothing when they tried to be romantic (or more). Her friends tried to console her, but many of them just talked behind her back about Chika being weird, leaving her more anxious and alone than ever. College seemed to be shaping up to be more of the same until Chika met Shinobu Ishii. She's a psychology professor and openly asexual. Through her, Chika begins to understand herself and finds a community of friends and peers who truly understand her.
